DAVID A. RITCHIE, OF GENT-RALIA, ILLINOIS, ASSIGNOR TO ECO1\TOMY ADVERTISING I COMPANY, OF. CENTRALIA, ILLINOIS, A CORPORATION OF ILLINOIS.

I ADVERTISING-MACHINE;

To all whom it may concern:

Be it known that I, DAVID A. Rrronm, a citizen of the United States, residing at Centralia, Illinois, have invented a certain new and useful Improvement in Advertising-Machines', of which the fo llow1ng 1s a full, clear, and exact description, such as will enable others skilled in the art towhich it appertains to make and use the same.

This invention relates to machines of the type that are used for projecting pictures or other subject-matter onto a screenor other suitable surface located some distance away from the machine, and particularly, to machines of the type that comprise a rotatable drum. equipped with transparent picture slides, a condenser and a source of light arranged inside of the drum and a is to provide a machine of the type referred to that is particularly adapted for general advertising purposes, in that it is easy to adjust and is not liable to get out of order when in use. I

Another object is to providean inexpensive machine of the general type referred to, in which the projecting apparatus, the

condenser, the lighting unit and the reflector that cooperates with the lighting unit are mounted in a novel manner that permits said elements to be adjusted easily. Other objects and desirable features of my invention will be hereinafter pointed out.

Figure 1 of the drawings is a vertical longitudinalsectional view of an advertising machine constructed in accordance with my invention.

Fig. 2 is a horizontal sectional view of said machine; and

Fig.3 is a perspective view, illustrating a portion of the drum of the machine' Referring to the drawin s, which illustrate the preferred form 0 my invention, A designates the drum' of the machine, which is preferably rotatably mounted in a closed casing B of. rectangular shape.

A projecting apparatus C is mounted on mounted on theperiphery of the drum in.

alinement with openings 2 therein, and

means is provided for rotating the drum intermittently, so as to bring the slides G into operative position between the projecting apparatus C and the cendenser D.

Specification of Letters Patent. Patented July 10, 1917, Application filed August QB, 1916. Serial No. 117,252.

The drum A is preferably constructed of I sheet metal and the two side members 3 thereof areprovided with hubs 4 that revolve freely on a stationary, horizontallydisposed shaft 5 which is supported by hollow brackets 6 on the side walls of the casing B, which brackets are equipped with collars 6 that bear against the ends of the hubs 4 on the drum, and thus hold the drum .centered with respect tothe casing B. The slides G are preferably removably mounted on the periphery of the drum, so that they can be arranged in different positions or be replaced by different slides, and while it is immaterial what means is employed for holding the slides in position, I prefer to provide the drum with pairs of angleshaped clips 7 that embra'cethe longitudinal edge portions of the slides, a pair of clips- 7 being provided for each slide, and the slides being prevented from moving longitudinally of their supporting clips by means of spring arms 8 that lap over the ends of the slides. The arms Scan be formed conveniently from pieces of spring wire that are soldered or connected in any other suitable manner to the clips 7, as shown in Fig. 3.

The condenser, the lighting unit and the reflector are adjustably mounted on a structure arranged inside of the drum and carried by the shaft on which the drum revolves, which structure is preferably composed of pieces of pipe or tubing and pipe fittings that are detachably connected together in such a manner that the condenser,

lowered, can be moved horizontally toward lighting unit and reflector can be raised or 'the lamp circuit, said various angular positions. The main sup porting element of the'structure referred to consists of a horizontally-disposed member 9 that passes through asleeve 10 mounted on the upper end of an upright 11 which is stationarily mounted on the shaft 5, the member 9 being adapted to be adjusted horizontally or longitudinally of its length in the sleeve 10. The condenser 13 is carried by a rod 12 adjustably mounte in a'sleeve 13 which is carried by a sleeve 14 that is adjustably mounted on the main supporting element 9 of the structure, the lighting unit E is carried by a rod 15 that passes through a horizontally-disposed sleeve 16 carried by a vertically-disposed sleeve 17 adjustably mounted on a vertical support 18-that depends from a sleeve 19 which is adjustablymounted'on the main supporting element 9, and the reflector F is carried by a rod 20 that passes through a vertically-disposed sleeve 21 carried by a sleeve 22 which is adj ustably mounted on the supporting member 9. The various sleeves above referred to preferably consist of T-shaped pipe fittings, and set screws or other suitable fastening devices 25' are employed to adjustably connect said sleeves to the rods or parts that pass through same. The condenser D is pivotally connected to the rod.12, so that it can be swung sidewise with relation to said rod, and the reflector Fis also pivotally connected to the part 20 that carries same, so that it can beswung upwardly and downwardly, and thus enable it to beadjusted accurately to the lighting unit E with which it cooperates. Any suitable clamping means can be used to hold the condenser and reflector in adjusted position, such, for example, as wing nuts 26 on the bolts that connect the condenser and reflector to the parts that carry same.

The projecting apparatus C comprises portions 27 and 28 that arepivotally connected together at 29, and the portion 27 is adjustably mounted in parallel guides 30 on the front wall of the casing of the machine, thereby enabling the projecting apparatus to be adjusted easily into proper position, by raising or lowering the portion 27 or by swinging the portion 28 on its pivots, said parts being so constructed that they are held in adjusted position by frictional pressure. The shaft 5 on which the drum is mounted is hollow, so that the electrical 'conduct0rs,31 which sup ly current to the lighting unit E can be ed into the drum through said shaft, as shown in Fig. 2, and a switch 32 is provided for governing switch being arranged inside of the casing B, as shown in Fig. 1, and the portions of the conductors 31 that extend from said switch to the shaft 5 being incased in a conduit 33. The

, Side members 3 of the drum are provided,

with-openings 34 through which the air in i the drum and in the casing can circulate,

and air inlet openingsand outlet openings '35 and 36, respectively, are formed in the pose consisting of an electric motor, 37 arranged inside of the casing B, as shown in Fig. 1, and connected by means of a belt 38 t with a pulley 39 on a shaft 40 equipped with a worm 41 which meshes with a gear 42 on a shaft that is provided with a disk 43, to which a pawl 44 is eccentrically connected. The pawl 44 cooperates with pins 45 that project laterally from one side or the drum A, and a coiled spring 46 is employed for normally holding said pawl in position to cooperate with said pins. When the motor 37 is in operation the pawl 44 moves upwardly and downwardly and cooperates with the pins 45 in a well known manner to impart a step by step movement to the drum A. The pawl 44 is guided by a bracket 47 on the rear wall ofthe casing B, and a friction brake 48 is arranged in the upper portion of the casing in the manner shown in Fig. 1, so as to exert sufficient frictional pressure on the drum to prevent it from overthrowing, said brake being pro- Vided with a turn buckle or other suitable means 49 that can be adjusted s0 as to vary the frictional pressure that the brake-exerts on the drum. Doors 50 are formed at suitable points in the walls of the casing B, so as to enable the slides in the periphery of the drum to be changed and the supporting structure for the condenser, the lighting unit and the reflector to be adjusted. The electrical conductors that lead to the motor 37 are preferably incased in a conduit 33 arranged inside of the casing, and a switch 51 is provided for controlling the motor circuit.
